To all whom it may concern:

Be it known that I, WILLIAM C. BALL, a citizen of the United States,residing at Ewing, in the county of Jackson, State of Indiana, haveinvented certain new and useful Improvements in Portable Swings; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to portable swings and has for an object toprovide a foldable swing frame in combination with a removable swingseat to permit of the swing being collapsed into a small compact bundlefor storing or shipping.

A further object is to provide a collapsible swing frame having the legsadjustably connected together in such a manner as to permit of the legsbeing rocked from divergent relative position to about parallel relativeposition and vice versa.

With the above objects in view the invention consists of certain noveldetails of construction and combination of parts hereinafter fullydescribed and claimed, it being understood that various modificationsmay be made in the minor details of construction within the scope of theappended claim.

In the accompanying drawings illustrating this invention: Figure 1 is afront elevation of the swing. Fig. 2 is a side elevation of the swing.Fig. 3 is a front elevation of the swing frame collapsed. Fig. 4 is aside elevation of the swing frame collapsed. Fig. 5 is a cross sectionalview on the line. 55 Fig. 1. Fig. 6 is a cross sectional view on theline 66 Fig. 2. Fig. 7 is a cross sectional view on the line 77 Fig. 1.Fig. 8 is a cross sectional view on the line 88 Fig 2. 5?

Referring now to the drawings in which like characters of referencedesignate similar parts, the swing frame is shown to comprise four legs10. each pair of legs on the same side of the frame being pivotallyconnected atthe upper ends to a side plate 11 by means of pivot pins 12.There are arcuate slots 13 formed in the side plate concentric with thepivot pins, these slots slidably receiving guide pins 14 carried by thelegs whereby the legs may be rocked outwardly on their pivots todownwardly divergent relation or may be rocked inwardly on their pivotsto downwardly convergent relation. The pair of front legs and also thepair of i'ea1"le'gsare connected by respective pairs of crossed links 15and 16 pivotally connected at their crossing as shown at 17 the upperends of the links being pivotally connected to the respective legs bypivot pins 18-and the lower ends of the links having longitudinal slots19 through which pass guide pins 20 carried by the legs. These pairs ofcrossed links may be collapsed by pressing the side plates 11 towardeach other whereby the front legs will be moved toward each other inparallelism as will also the rear legs and facilitate the frame beingcollapsed into a small'compact bundle for shipping or storing. Byforcing the side plates 11 away from each other the crossed links areextended whereby the legs are forced bodily outwardly and caused toassume the usual divergent position. The swing seat 21 is provided onthe sides with the usual swing arms 22 each of which is provided at theupper end with a hook 23 which is removably engaged in an opening 24formed in the related side plate 11.

In operation suppose that the swing is in set up or operative positionas shown in Figs. 1 and 2 and it is desired to collapse the swing forstoring or shipping into the com- ,pact bundle shown in Figs. 3 and 4.The

arms 22 are bent toward each other at the upper ends and raised slightlyuntil the hooks disengage from the side plates whereupon the seat may bebodily removed from the frame. The front and rear legs on each side ofthe frame are now rocked toward each other until they assume thedownwardly convergent relation shown. The pair of front legs and thepair of rear legs are now moved toward each other by pressure upon theside plates until they assume the substantially parallel juxtaposedposition shown. To set up the frame the above operation is reversed.

From the above description it will be seen that I have provided anextremely simple and effective collapsible swing which may be collapsedinto a small compact bundle for storing and may be readily set up whendesired without inserting any screws, bolts or similar devices.

1 WVhat' is claimed, is :v

In a swing, frame comprising a pair of front andrear legs, plates,-thelegs of each pair having their upper ends pivotally connected to theplates, said plates having slots formed therein below the pivotalconnection ed to the legs, and a seat removably asso- 10 with the legs,pins carried by the legs and ciated With the plates.

slidably engaged in the slots to limit the In testimony whereof, I aflixmy signaswinging movement of the legs in opposite ture, in the presenceof two witnesses.

-' directions, a pair of links for each pair of WILLIAM 0 BALL legs,said links being pivotally connected at their centers and having theirupper ends Witnesses:

pivotally connected to the legs, and their EDWIN B. BALL, lower endsslidably and adjustably connect- CHARLES H. BARKMAN.
